Hereinafter, a system for performing a sleep surface temperature control method according to an embodiment of the present invention will be described in detail with reference to FIG.

In a temperature control system (100) for a sleeping surface for performing a sleeping temperature control method, a temperature control system (100) for performing a sleeping temperature control method is provided. The user 200 receives a user set temperature for a sleeping appliance from the user 200, A control module 110 for controlling the temperature of the sleeping article to a first sleeping temperature and controlling the temperature of the sleeping utensil to a second sleeping temperature after a predetermined period of time and at least one of a mattress, And the sleeping article may further include the wearable device 130 for the body temperature of the user 200. [

At this time, the control module 110 may include a timer 120 for checking the temperature control time and setting the time.

For example, the user 200 can set a specific temperature to a desired temperature and input the temperature to the control module 110. The control module 110 controls the temperature of the sleeping appliance 140 Temperature can be adjusted.

Thereafter, the control module 110 maintains the temperature of the sleeping article 140 corresponding to the temperature inputted by the user 200 for a preset time (30 minutes), and when the predetermined time passes, The temperature of the sleeping article 140 can be controlled at a temperature of two degrees lower than the temperature of the sleeping article 140. [

Thereafter, the temperature of the user 200 may be maintained at 2 degrees lower than the temperature input by the user 200 from 5 to 6 o'clock in the morning, and may be increased by 2 degrees in accordance with the time of the user 200.

(NREM, deep sleep) as the body temperature is rapidly lowered when the user takes a sleeping surface by inducing a change in body temperature in accordance with a change in the temperature of the sleeping article 140 used in the external environment, This can accelerate the sleeping of the high quality.

To raise the temperature of the sleeping article 140 during the wake-up time of the user 200, the temperature of the body entering the water surface is expressed by the warm regulation (warming up of the body temperature) , And the temperature of the sleeping article 140 is increased by 2 degrees to restore the external temperature environment and to facilitate the thermal regulation (body temperature automatic adjustment function) to provide a sleeping function.

Hereinafter, the correlation between the sleep pattern analysis and the body temperature and the external temperature according to an embodiment of the present invention will be described in detail with reference to FIG. 2 to FIG.

There are two types of human body temperature: internal body temperature and skin body temperature. Keeping the internal body temperature as low as possible during the sleeping time is closely related to improving the quality of the sleeping water. It starts when it grows. Therefore, if the temperature of the sleeping article 140 is lower than the measured temperature by 0.5 ° C - 1 ° C so that the internal body temperature can be rapidly lowered at the start of the sleeping, it may be helpful to start the sleeping after a certain time.

That is, the more the internal temperature is lowered, the longer the NREM and DEEP SLEEP times can improve the quality of sleep.

The correlation coefficient between internal body temperature and skin temperature varies according to the person and situation, but it is known to move in the same direction from 0.3 to 0.88. Humans have automatic temperature control function (THERMOREGULATION) The temperature of the sleeping article 140 can be more positively utilized at the time of REM sleep because the user is more sensitive to external environmental factors such as the sleeping article 140 temperature and the room temperature.

Referring to FIG. 2, it can be seen that a graph of the sleep period can be confirmed. When the user enters the water surface, the NREM sleep state 320 and the REM sleep state 310 are repeated 4 to 5 times.

Referring to the time series analysis graph of the body temperature in FIG. 3, it can be seen that the body temperature changes in the same pattern as the sleep cycle according to the time change through the time series analysis based on the sleep cycle pattern classification.

That is, the sleep cycle can be defined by the body temperature change with time, and the pattern can be seen when the temperature gradually decreases and then goes up again.

The sleep cycle can consist of NREM (Light Sleep, Deep Sleep, Very Deep Sleep) and REM stages in general.

2 to 3 are sleep cycle pattern classifications composed of an NREM sleep state 320 and a REM sleep state 310 as a result of analyzing body temperature data with the passage of time.

Referring to FIG. 4, in the case of a deep sleep, the correlation between the body temperature and the external temperature can be confirmed.

The Deep Sleep effect factor is extracted through PCA analysis (Principal Component Analysis), but Deep Sleep (sleeping phase) may occur only when the correlation between body temperature and external temperature (sleeping article temperature) is high.

As the optimum temperature range, we can see that the Deep Sleep phase is most frequently expressed in the 18 to 20 degree distribution band.

Since the body temperature is a variable that varies with the passage of time during the sleeping time of the user 200, a time series analysis using the measured body temperature as a time series variable is performed and then decomposed into elements of trend and seasonal, ) You can check the time category.

Also, according to the above-described analysis, the length of the sleeping time can be prolonged as the length of the sleeping time is long and the correlation between the internal body temperature and the external temperature (the temperature of the sleeping article) becomes larger.

Hereinafter, a method for controlling a temperature for a sleeping state according to an embodiment of the present invention will be described in detail with reference to FIG.

The temperature of the sleeping appliance is controlled to the first sleeping temperature after a predetermined time has elapsed after receiving the set temperature of the user 200 for the sleeping appliance from the user 200.

The system receives the set temperature of the user 200 for the sleeping article from the user 200 (S510).

In a further embodiment of the present invention, instead of receiving the user 200 set temperature for the sleeping article from the user 200 when the user 200 worn the wearable device capable of measuring the body temperature of the user 200, The temperature control system for sleeping can measure the body temperature of the user 200 by the wearable device and automatically input and control the temperature of the sleeping article to a temperature higher than the body temperature of the user 200. [

At this time, the body temperature of the user 200 is derived from the skin temperature of the user 200, and the controlled temperature can be controlled to be 0.5 to 1 degree higher than the skin temperature of the user 200.

Thereafter, the temperature of the sleeping utensil can be controlled to the first sleeping temperature after a predetermined time passes (S520).

The predetermined time may be 20 to 30 minutes, which is a time point at which the body temperature is raised due to the influence of the sleeping article 140, generally in the case of a strong general person.

In this case, the first sleeping temperature is a temperature lower than the preset temperature of the user 200, and may be preferably a set temperature of the user 200 or a temperature which is 1.5 to 2 degrees lower than the body temperature of the user 200.

In a further embodiment of the present invention, when the user 200 wears a wearable device capable of measuring the body temperature of the user 200, regardless of the predetermined time, the body temperature of the user 200 is lower than the initial temperature of the sleep The temperature of the sleeping article can be controlled by the first sleeping temperature. Further, it is possible to grasp the time when the REM sleep starts and to control the sleep temperature to the 1-1 sleep temperature lower than the first sleeping temperature.

At this time, the time at which the REM sleep starts may be derived based on the sleeping data pattern derived using the past sleeping data analysis information. Preferably, the 1-1 sleep surface temperature may be 2 to 2.5 degrees lower than the body temperature of the user 200, and the time at which the REM sleep starts in a healthy general person may be 1 hour to 1 hour 30 minutes.

Further, it is possible to grasp the time when the NREM sleep surface is started, and to control the temperature to the 1-2 sleep surface temperature higher than the 1-1 sleep surface temperature. At this time, the starting point of the NREM sleep surface can be derived based on the sleep surface data pattern derived using the past sleep surface data analysis information. The first 1-2 sleeping temperature is preferably 1.5 to 2 degrees lower than the body temperature of the user 200.

In addition, the temperature of the sleeping article 140 can be changed in accordance with the body temperature in the manner of the above-described additional embodiment of the present invention for each step of the sleep cycle which is repeated three to four times until the predetermined time.

The predetermined time may preferably be 5 to 6 o'clock in the morning.

After the predetermined time passes after the control is performed to the first sleeping temperature, the temperature of the sleeping appliance can be controlled to the second sleeping temperature (S530).

The second water surface temperature is a temperature higher than the first water surface temperature, and preferably 0.5 to 1 degree higher than the body temperature.
